Al-Lu'lu Wal-Marjan 1754 — The Book of At-Tauba (the Repentance)

Abu Hurairah Narrated from:

I heard the Prophet صلى الله عليه وسلم saying, "If somebody commits a sin and then says, 'O my Lord! I have sinned, please forgive me!' and his Lord says, 'My slave has known that he has a Lord Who forgives sins and punishes for it. I therefore have forgiven my slave (his sins).'Then he remains without committing any sin for a while and then again commits another sin and says, 'O my Lord, I have committed another sin, please forgive me.,' and Allâh says, 'My slave has known that he has a Lord Who forgives sins and punishes for it. I therefore have forgiven my slave (his sin).'Then he remains without committing another sin for a while and then commits another sin (for the third time) and says 'O my Lord, I have committed another sin, please forgive me,' and Allâh says, 'My slave has known that he has a Lord Who forgives sins and punishes for it. I therefore have forgiven My slave (his sin), he can do whatever he likes." [1] ( Sahîh Al-Bukhârî, Hadîth No. 598, Vol. 9 )
